AQD Chief attends

inauguration at MOAP

AQD Chief Dr. Joebert Toledo attended the

inauguration of Misamis Occidental Aquamarine Park’s (MOAP) multi-species hatchery last January 5. This hatchery is a joint project of the Misamis Occidental provincial government, Australian government and the Department of Agriculture through SEAFDEC/AQD.

AQD was tasked to: (1) provide technical support, (2) provide science-based aquaculture technologies, and (3) supervise the project. Also, AQD’s engineering section designed the multi-species hatchery.

Mr. Stephen Scott, Minister and Deputy

Head of Mission of the Australian embassy visited AQD on January 22, meeting with AQD Chief Dr. Joebert Toledo, Research Head (RD) Dr. Evelyn Grace DJ-Ayson, and Administration & Finance Head (AFD) Atty. Jerry Opinion.

Mr. Scott was mostly interested to know about AQD’s participation in the multi-species hatchery project in Misamis Occidental. He inquired about the contributions of AQD to the project, how the project started, what species will be

raised in the hatchery, and ������������� �������������the community.

The visit of Mr. Scott to AQD is part of the Australian embassy’s scheduled appointments to

representatives of Philippine government agencies, academe, international and non-governmental organizations to discuss local politics, security, and development issues.

NCSU professor

visits AQD

North Carolina State University (NCSU)

professor Dr. Russell Borski visited AQD last January 23-27 to discuss the progress of the existing collaborative project between NCSU and AQD entitled Alternative feeding ��������������� �����������������������������������������. Dr. Borski is the Principal Investigator and AQD RD head Dr. Evelyn Grace DJ-Ayson is the host country Co-principal Investigator for the project.

����������������������Dr. Borski together with Dr. Ayson went to Igang Marine Station to see the

�������������� ���������experiments which will be started this February. The next day, he met with seaweed farmers of Sibunag, Guimaras. These farmers were the ��������������������������workshop (which is also part of the collaborative project) conducted by AQD’s Dr. Anicia Hurtado. Dr. Borski also surveyed the seaweed farms in Sibunag.

Dr. Borski had a meeting with Dr. Ayson, Ms. Milagros Castaños (Devcom head), and Ms. Kaylin Corre (OIC TID head) on the 26th to discuss podcasting as a new extension tool. During the meeting,

Dr. Borski also showed his initial efforts on tilapia book review podcast.

On that day, Dr. Borski also had a dinner meeting with AQD Chief Dr. Joebert Toledo, Dr. Ayson, Ms. Corre, and Dr. Ma. Junemie Hazel Ramos (Aquatic Ecology Program Leader) at Breakthrough.

Lastly, Dr. Borski conducted a research seminar on ����������������������������������������for improving production ������������� (see summary on page 3) at the RD AV room on the 27th.

AQD researcher Ms. Antonieta

Evangelista presented a paper on “Growth and survival ��������������Clarias ������������ (Gunther) fry reared at different stocking densities and feeding regimes in Laguna de Bay, Philippines” in the international symposium in Can Tho University, Can Tho City, Vietnam. AQD’s Mr. Ruel Eguia is also among the conference’s participants.

The ���������������������������������������������������������������

development conference was held last December 5-7, 2008.

The conference organizer was Can Tho University in collaboration with NACA (Network of Aquaculture �������������!"����#��

ASEM (Asia-Europe Meeting) Aquaculture Platform, and PhysCAM Project of DANIDA (Danish International Development Agency). The government and other local institutions in Vietnam also supported the event.

In joining the conference, AQD participants gained knowledge and gathered relevant information on the ���������������������������aquaculture. It also expanded AQD’s network of contacts for future collaborations.

Upon AQD’s advise, Mr. Nepomuceno replaced his pond’s primary and secondary wooden gates,

fabricated screens and wooden slabs, cleared the dikes of weeds, levelled the pond bottom, readied the ponds for fertilization and liming, repaired eroded dikes, and positioned the pond’s main gate strategically.

Other AQD participants of the seminar were Dr. Mae Catacutan, Ms. Kaylin Corre, and Ms. Delia Tubo. Some AQD staff were also present as observers.

In participating in this event, AQD was also able to sell its books and manuals.

Eguia, Mr. Ruel Eguia, and Ms. Antonieta Evangelista participated in the international symposium on Current �����������������������������last January 20. The conference was held at the Philippine Carabao Center, CLSU (Central Luzon State

University), Nueva Ecija.The purpose of the

conference is to disseminate results of collaborative studies between CLSU and the National Taiwan University under the Microsatellite and Otolith (MO) project.

The topics presented in the conference were mostly on population genetics as

applied in the conservation and management of freshwater ����*

In joining this event, BFS participants were able to: (1) gather relevant concepts and techniques that can be applied to BFS’s current research projects, and (2) meet researchers who are interested in collaborating with AQD.- FROM THE REPORT OF MRR EGUIA

Compensatory growth is a period of growth acceleration that occurs when animals are alleviated of a previous growth-stunting condition. The study on hybrid striped bass show that restoration of normal feeding and/or temperature following

growth-stunting conditions (i.e. feed restriction and/or low temperature) elicits a robust compensatory growth response. It is accompanied by increase in growth rate, increase in appetite, and improved feed conversion. Thus, compensatory growth may be used as basis to modify the feeding prpprppp otocol to reduce production cost. > > to page 444

Broodstock diet of mangrove red snapper with squid meal showed superior performance compared to white fish mealbased on percentage of: (1) fecundity and (2) normal eggs produced. The study also shows that mangrove red snapper broodstock fed with diethaving squid meal improved: (1) egg production, (2) hatching rate, and (3) cumulative survival rate. On the other hand, freshwater prawnbroodstock fed with squid oil-corn oil combination showed higher fecundity and increase in production & survival rate of larvae than those fed wiww th corn oil alone. Hence, the researchers recommend feeding g of squq id or sqquid meal diets to broodstocks.

Arachidonic acid (ArA) is an essential fatty acid but a minor component especially in cold and temperate water species. However, it was foundout that ovaries, eggs, and fry of tropical fishes like mangrove red snapper, rabbitfish, coral trout and striped jack have intermediate or high ArA levels and relatively low EPA (eicosapentoic acid) levels. Moreover, the result also showed that ArA is a major fatty acid component in mangroveand coral reef organisms. Hence, it is possible that dietary ArA is essential to improve egg production and larval quality of tropical fishes. Theresearchers proposed 3.5 of ArA/EPA ratio and 2.1 of DHA/ArA ratio as the optimum ratios of broodstock diets in tropical fish.

Organic osmolytes, including taurine and betaine, are involved in adaptation by a variety of organisms to hyperosmotic conditions encountered during the accumulation of wastes. A study was conducted to determine if Atlantic salmon possess genes that encode similar transport proteins required to import these osmolytes into their cells. The result shows that taurine and its transporter has a role in hyperosmotic adaptation in Atlantic salmon while betaine transporter has none.

Heat shock proteins (hsps) are responsible in helping fold newly made proteins. They also act as molecular chaperones. Hsps are induced under certain forms of stress (including heat stress); hence, are used as indicators of general stress in this study. Atlantic salmon were exposed to common forms of hatchery stress (i.e. cold stress, crowding, and capture stress) and responses of hsp30, 70, and 90 were measured. The result shows that no spspspspppecece ific betaine transpppporter was identified in the salmon sppppecies studied.
